Amazon Lambda

AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers, automatically scaling and executing your code in response to events from over 200 AWS services and SaaS applications while you pay only for the compute time you consume.

Amazon Lambda publishes 2 APIs on the APIs.io network: Event Source Mappings API and Functions API. Tagged areas include Compute, Event-Driven, FaaS, Functions, and Serverless.

The Amazon Lambda catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Amazon Lambda’s developer surface includes authentication, developer portal, documentation, support, engineering blog, developer console, signup flow, and 27 more developer resources.
